Struct PinChallenge 

pub struct PinChallenge { /* private fields */ }

NDNCERT PIN/OTP challenge handler.

Single-round: the client submits { "code": "<pin>" } and the CA checks the SHA-256 hash against the stored value.

pub fn new(pin: &str) -> Self

Create a challenge from a plaintext PIN (hashed internally).

pub fn new_with_max_tries(pin: &str, max_tries: u8) -> Self

Create a challenge with an explicit attempt limit.
